Recently I ordered a few old grey short swords off bricklink, (the ones they stopped making a couple decades before I was born

) With them though, i got a sword that is light grey, but is made of the new plastic and uses the sword mold that does not have the diamond shaped cross-section. I didn't think they put a sword like this in any set, so does any one know where this came from?
